DERBY — As determined by the ballot and by anecdotal evidence, a large percentage of Derby residents favor the new Walmart Super Center slated for construction on Route 5. But that doesn’t mean some don’t have serious reservations about the project.

Those reservations, particularly ones concerning how the 160,000-square-foot store will affect traffic and the economy of the town were well aired in a pair of hearings held at the Derby Municipal Building Monday and Tuesday.
